I am building a text-to-speech application that works seamlessly on iOS, Android, and any modern web browser. The core of the project is a single code-base (or tightly aligned native builds) that can read user-supplied text aloud while giving end users meaningful control over how that voice sounds. Core functions to implement • Voice customisation: different accent options, male and female voices, plus real-time pitch and speed sliders. • Language selection: users should be able to switch between multiple languages from a clean, searchable menu. • Save audio: once the text is rendered to speech, users can download the resulting audio file locally or share it. Acceptance criteria 1. A fully compiled app is available in TestFlight, an Android APK (or Play Internal Testing track), and a responsive web build behind a test URL. 2. Recorded speech must reflect selected accent, gender, pitch and speed with no noticeable artefacts. 3. The web and mobile versions share identical feature sets and consistent UI/UX. 4. Saved audio files download in a common format (MP3 or WAV) and play on default OS players. Source code should be version-controlled (GitHub or GitLab) with clear build instructions so I can replicate the releases myself. If you prefer Flutter, React Native, Swift/Kotlin plus a separate React/Vue/Angular front-end—or another well-supported tech stack—please note it in your approach; I’m open as long as performance and maintainability stay high. That’s the full scope; once the above milestones are met and tested, the project is complete.

Hello, I can build this cross-platform text-to-speech application exactly as you’ve scoped it, with a single, maintainable codebase and identical features across iOS, Android, and Web. Recommended approach Primary stack (my recommendation): Flutter → one codebase for iOS, Android, and Web with consistent UI/UX Native TTS engines (Apple AVSpeechSynthesizer, Android TTS, Web Speech API or cloud fallback) Optional cloud TTS provider (for higher-quality voices & accents, if needed) This avoids feature drift and keeps build/release simple. What I’ll implement Core features Voice customisation Male/female voices (where supported) Accent selection Real-time pitch & speed sliders (no artefacts) Language selection Searchable language menu Dynamic voice availability per language Audio export Generate and download/share MP3 or WAV Plays in default OS players Platform parity Same controls, same UI, same behaviour on web + mobile Responsive layout for browser use Acceptance-ready deliverables ✅ TestFlight build (iOS) ✅ Android APK / Internal Testing build ✅ Web build on test URL ✅ GitHub/GitLab repo with: Why hire me? I focus on audio fidelity, predictable behaviour, and clean releases—not just “it works on my device.” Your acceptance criteria are concrete, and I build to pass them cleanly. Timeline (typical) Core TTS + UI: 2–3 weeks Audio export + cross-platform parity: 1–2 weeks Testing & builds: ~1 week Happy to start immediately.

Hi! I can build your TTS app using Flutter to ensure a single codebase for iOS, Android, and Web with 100% UI consistency.
